Is GAE down?

[Jeremy Hua]

My GraphQL endpoint https://staging-dot-humb-app.appspot.com/graphql is sometimes up returning {"errors":[{"message":"Cannot read property 'split' of undefined"}]} as expected on browser and correct responses on my app. However, every alternate request is returning

Error: Server Error

The server encountered a temporary error and could not complete your request.

Please try again in 30 seconds.

Its nodejs server on a flexible environment exposing the graphql endpoint.

Google App Engine does not seem to be down. In case this error could originate from your Node.js implementation, can you provide a minimal working example of your code demonstrating this issue?

Alternatively, you can verify the status of the endpoint you are triggering by sending it a request as demonstrated in this Quickstart for Cloud Endpoints Frameworks on App Engine.
